Argyranthemum plant named ‘PB1V2’

ABSTRACT

A new and distinct cultivar of  Argyranthemum  plant named ‘PB1V2’, characterized by its compact, uniform, outwardly spreading and mounded plant habit; freely branching growth habit; freely flowering habit; anemone-type inflorescences with pale yellow-colored ray florets and golden yellow-colored disc florets; and good garden performance.

Botanical designation: Argyranthemum frutescens.

Cultivar denomination: ‘PB1V2’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Argyranthemum plant, botanically known as Argyranthemum frutescens and hereinafter referred to by the name ‘PB1V2’.

The new Argyranthemum is a naturally-occurring whole plant mutation of a proprietary selection of Argyranthemum frutescens identified as code number X98060.3, not patented. The new Argyranthemum was discovered and selected by the Inventor as a single plant within a population of plants of the selection X98060.3 in a controlled environment Balmoral Village, New South Wales, Australia in October, 2002.

Asexual reproduction of the new Argyranthemum by vegetative tip cuttings in a controlled environment in Balmoral Village, New South Wales, Australia since 2002 has shown that the unique features of this new Argyranthemum are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar PB1V2 have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘PB1V2’. These characteristics in combination distinguish ‘PB1V2’ as a new and distinct potted Argyranthemum cultivar:

-   -   1. Compact, uniform, outwardly spreading and mounded plant         habit.     -   2. Freely branching growth habit.     -   3. Freely flowering habit.     -   4. Anemone-type inflorescences with pale yellow-colored ray         florets and golden yellow-colored disc florets.     -   5. Good garden performance.

Plants of the new Argyranthemum differ from plants of the parent selection in the following characteristics:

-   -   1. Plants of the new Argyranthemum are more compact than plants         of the parent selection.     -   2. Plants of the new Argyranthemum have anemone-type         inflorescences whereas plants of the parent selection have         single-type inflorescences.

Plants of the new Argyranthemum can be compared to plants of the Argyranthemum cultivar Midas Gold, disclosed in U.S. Plant Pat. No. 11,773. In side-by-side comparisons conducted in Balmoral Village, New South Wales, Australia, plants of the new Argyranthemum differed from plants of the cultivar Midas Gold in the following characteristics:

-   -   1. Plants of the new Argyranthemum were shorter than plants of         the cultivar Midas Gold.     -   2. Plants of the new Argyranthemum had anemone-type         inflorescences whereas plants of the cultivar Midas Gold had         single-type inflorescences.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Argyranthemum. These photographs show the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Argyranthemum.

The photograph at the bottom of the sheet comprises a side perspective view of a typical flowering plant of ‘PB1V2’.

The photograph at the top of the sheet is a close-up view of typical inflorescences of ‘PB1V2’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown in an outdoor nursery during the summer in Bonsall, Calif. and under conditions and practices which approximate those generally used in commercial potted Argyranthemum production. During the production of the plants, day temperatures ranged from about 18° C., to about 38° C., and night temperatures ranged from about 16° C. to 24° C. Plants were pinched one time. Plants used in the photographs and for the description were about nine weeks old. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
